摘　　要：紧水滩水电站2台机组先后出现发电机定子硅钢片径向滑出,割破线棒绝缘,导致发电机定子接地。检修中对定子铁心压紧度、温度变化与通风情况进行了检查分析,并采取了相应措施,取得较好效果。The silicon steel sheets of stators of two hydro-generators in Jinshuitan Hydropower Station have been slid out radially in operation. The slide-out sheet cuts the insulation of bars and results the accident of stator grounding. The core compression, temperature variation and ventilation of stator are analyzed for finding the cause of accident and appropriate measures are taken to treat it. The actual operation shows that the treatments are better.
